Vancouver will be a delightful place to live following the pole shift, with a far warmer climate, spared ice and snow in the winter, and close to the coastline as it is at present. Rising water following the polar melt will spare much of the mountains surrounding Vancouver, making the step out of the rising water fairly easy for survivors to deal with. For Vancouver, the issue is not being positioned after the shift, but surviving the shift itself. The West Coast in general will suffer from rapid subduction that will melt the rock in low lying places, due to heat from friction, and many local Indian tribes have tales and myths of such times. Tidal waves will assault the area, and volcanoes up and down the coast, dormant and active alike, will explode. Those who would survive might consider moving inland for the shift itself, and then returning. Be advised that bridges and roads will not be passable, so the return trip should be anticipated to be essentially on foot.
Vancouver Island has added drama as the Juan de Fuca plate will separate under the pressure of subduction and act as a separate entity from both the North America and the Pacific plates. This is the reason for the island having been created in the first place, during prior shifts. Because activity is compression, with the Juan de Fuca plate and the North American plates riding over plates sliding under, legends relay hot earth and boiling rivers. This will be less of a problem during this shift than in the past, as protecting layers of rock have already been pushed under the island. Nevertheless, two activities the coast will not have to deal with will be presented on the island:
After the shift and the polar melt, the island will find itself with more area above the 675 foot area, having gained 100 or more feet of sea level during the compression.
